Ecological role and services of tropical mangrove ecosystems: a reassessment

Abstract: Aim To reassess the capacity of mangroves for ecosystem services in the light of recent data. Location Global mangrove ecosystems. Methods We review four long-standing roles of mangroves: (1) carbon dynamics – export or sink; (2) nursery role; (3) shoreline protection; (4) land-building capacity. The origins of pertinent hypotheses, current understanding and gaps in our knowledge are highlighted with reference to biogeographic, geographic and socio-economic influences. Results The role of mangroves as C sinks needs to be evaluated for a wide range of biogeographic regions and forest conditions. Mangrove C assimilation may be under-estimated because of flawed methodology and scanty data on key components of C dynamics. Peri-urban mangroves may be manipulated to provide local offsets for C emission. The nursery function of mangroves is not ubiquitous but varies with spatio-temporal accessibility. Connectivity and complementarity of mangroves and adjacent habitats enhance their nursery function through trophic relay and ontogenetic migrations. The effectiveness of mangroves for coastal protection depends on factors at landscape/geomorphic to community scales and local/species scales. Shifts in species due to climate change, forest degradation and loss of habitat connectivity may reduce the protective capacity of mangroves. Early views of mangroves as land builders (especially lateral expansion) were questionable. Evidence now indicates that mangroves, once established, directly influence vertical land development by enhancing sedimentation and/or by direct organic contributions to soil volume (peat formation) in some settings. Main conclusions Knowledge of thresholds, spatio-temporal scaling and variability due to geographic, biogeographic and socio-economic settings will improve the management of mangrove ecosystem services. Many drivers respond to global trends in climate change and local changes such as urbanization. While mangroves have traditionally been managed for subsistence, future governance models must involve partnerships between local custodians of mangroves and offsite beneficiaries of the services.

Instruments to measure patient experience of health care quality in hospitals: a systematic review protocol

Abstract: Improving and sustaining the quality of hospital care is an international challenge. Patient experience data can be used to target improvement and research. However, the use of patient experience data has been hindered by confusion over multiple instruments (questionnaires) with unknown psychometric testing and utility. We conducted a systematic review and utility critique of questionnaires to measure patient experience of healthcare quality in hospitals. Databases (Medical Literature Analysis and Retrieval System (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Psychological Information (PsychINFO) and Web of Knowledge until end of November 2013) and grey literature were scrutinised. Inclusion criteria were applied to all records with a 10 % sample independently checked. Critique included (1) application of COSMIN checklists to assess the quality of each psychometric study, (2) critique of psychometric results of each study using Terwee et al. criteria and (3) development and critique of additional aspects of utility for each instrument. Two independent reviewers completed each critique. Synthesis included combining findings in a utility matrix. We obtained 1157 records. Of these, 26 papers measuring patient experience of hospital quality of care were identified examining 11 international instruments. We found evidence of extensive theoretical/development work. The quality of methods and results was variable but mostly of a high standard. Additional aspects of utility found that (1) cost efficiency was mostly poor, due to the resource necessary to obtain reliable samples; (2) acceptability of most instruments was good and (3) educational impact was variable, with evidence on the ease of use, for approximately half of the questionnaires. Selecting the right patient experience instrument depends on a balanced consideration of aspects of utility, aided by the matrix. Data required for high stakes purposes requires a high degree of reliability and validity, while those used for quality improvement may tolerate lower levels of reliability in favour of other aspects of utility (educational impact, cost and acceptability).

Turning the Tide: How Blue Carbon and Payments for Ecosystem Services (PES) Might Help Save Mangrove Forests

Abstract: In this review paper, we aim to describe the potential for, and the key challenges to, applying PES projects to mangroves. By adopting a “carbocentric approach,” we show that mangrove forests are strong candidates for PES projects. They are particularly well suited to the generation of carbon credits because of their unrivaled potential as carbon sinks, their resistance and resilience to natural hazards, and their extensive provision of Ecosystem Services other than carbon sequestration, primarily nursery areas for fish, water purification and coastal protection, to the benefit of local communities as well as to the global population. The voluntary carbon market provides opportunities for the development of appropriate protocols and good practice case studies for mangroves at a small scale, and these may influence larger compliance schemes in the future. Mangrove habitats are mostly located in developing countries on communally or state-owned land. This means that issues of national and local governance, land ownership and management, and environmental justice are the main challenges that require careful planning at the early stages of mangrove PES projects to ensure successful outcomes and equitable benefit sharing within local communities.

Visualization beyond the Desktop--the Next Big Thing

Abstract: Visualization is coming of age. With visual depictions being seamlessly integrated into documents, and data visualization techniques being used to understand increasingly large and complex datasets, the term "visualization"' is becoming used in everyday conversations. But we are on a cusp; visualization researchers need to develop and adapt to today's new devices and tomorrow's technology. Today, people interact with visual depictions through a mouse. Tomorrow, they'll be touching, swiping, grasping, feeling, hearing, smelling, and even tasting data. The next big thing is multisensory visualization that goes beyond the desktop.

Telemonitoring for chronic heart failure: the views of patients and healthcare professionals - a qualitative study.

Abstract: Aims and objectives To understand the views of patients and professionals on the acceptability and perceived usefulness of telemonitoring in the management of chronic heart failure in the context of day-to-day care provision. Background There is an increasing interest in the potential for telemonitoring to support the home-based management of patients with chronic heart failure. However, little is known about the views of patients and professionals on the use of telemonitoring in this context. A chronic heart failure telemonitoring service was set-up by NHS Lothian, Scotland, to evaluate the intervention. Design A qualitative design was adopted to explore the views of patients and professionals participating in the service. Methods Semi-structured interviews were undertaken with 18 patients (61% male, mean age 75 years) and five professionals participating at different time points in this new service. Interviews were audio recorded, coded and thematically analysed using the Framework approach. Results Five main themes were identified: ‘information, support and reassurance’; ‘compliance and dependence’; ‘changes and challenges’; ‘determining the criteria for patient applicability to telemonitoring’; and ‘continuity of care’. Conclusion Patients and professionals considered telemonitoring useful in the management of chronic heart failure, although with some caveats. Telemonitoring was popular with patients because they felt reassurance arising from what was perceived as continuous practitioner surveillance. Professionals expressed concern regarding perceived patient dependence on practitioner support. Increased workload was also a concern. Both groups acknowledged the need for improved technology and changes to service provision in order to better meet the intended objectives of the service. Relevance to clinical practice Although popular with patients, professionals emphasised the importance of case selection and adequate training and support, both for patients and themselves, in order to maximise the expected benefits of the service, particularly with regard to enabling self-management.

Organizational culture in knowledge creation, creativity and innovation: Towards the Freiraum model

Abstract: This paper draws on findings from an in-depth case study of practices related to the meeting of organizational goals pertinent to knowledge creation, creativity and innovation performance. Overall a mixed methods approach that used both quantitative and qualitative data was adopted in empirical research conducted within a large German manufacturing firm. A quantitative analysis of survey data highlighted factors necessary to nurture an environment conducive to knowledge creation, creativity and innovation. The organization should: be open to change; encourage and value free communication and new and/or unusual ideas; tolerate mistakes; and nurture intrinsically motivated staff. It should be supported by leaders who promote these characteristics as shared values, while challenging and empowering their staff to generate new ideas in a drive to further innovation. Further analysis of focus group and interview data in the same case study identified three main determinants that underpin knowledge creation and creativity: (1) structured 'space' that creates expertise and experience of individuals while working in routine; (2) willingness to innovate - individuals' propensity to experiment with ideas, even at risk of failure; and (3) authorized and dedicated 'space' designated specifically for individuals to explore new ideas ('Freiraum'). These findings have contributed to the development of a new articulation of the organization of creativity and innovation. It draws on established concepts from the domain of knowledge and creativity management, and extends these to deepen our understanding of how aspects of organizational culture, including leadership and social conditions, influence organizational performance in terms of (1) improving knowledge creation processes related to creativity, and (2) fostering innovation.

Requirements model driven adaption and evolution of Internetware

Abstract: Today’s software systems need to support complex business operations and processes. The development of the web-based software systems has been pushing up the limits of traditional software engineering methodologies and technologies as they are required to be used and updated almost real-time, so that users can interact and share the same applications over the internet as needed. These applications have to adapt quickly to the diversified and dynamic changing requirements in the physical, technological, economical and social environments. As a consequence, we are expecting a major paradigm shift in software engineering to reflect such changes in computing environment in order to better address the fundamental needs of organisations in this new era. Existing software technologies, such as model driven development, business process engineering, online (re-)configuration, composition and adaptation of managerial functionalities are being repurposed to reduce the time taken for software development by reusing software codes. The ability to dynamically combine contents from numerous web sites and local resources, and the ability to instantly publish services worldwide have opened up entirely new possibilities for software development. In retrospect to the ten years applied research on Internetware, we have witnessed such a paradigm shift, which brings about many changes to the developmental experience of conventional web applications. Several related technologies, such as cloud computing, service computing, cyber-physical systems and social computing, have converged to address this emerging issue with emphasis on different aspects. In this paper, we first outline the requirements that the Internetware software paradigm should meet to excel at web application adaptation; we then propose a requirement model driven method for adaptive and evolutionary applications; and we report our experiences and case studies of applying it to an enterprise information system. Our goal is to provide high-level guidelines to researchers and practitioners to meet the challenges of building adaptive industrial-strength applications with the spectrum of processes, techniques and facilities provided within the Internetware paradigm.

Do greenhouse gas emissions affect financial performance? – an empirical examination of Australian public firms.

Abstract: Previous studies that have attempted to relate corporate environmental performance to financial performance have generated conflicting results. This paper presents the findings of a study on the relationship between greenhouse gas (GHG) emissions and the financial performance of Australian corporations. Using multiple regression models and data from a sample of 69 Australian public companies, this paper finds a positive correlation between GHG emissions and corporate financial performance. By testing the statistical significance of GHG emission factors in determining company Tobin's q, this study finds that a stronger Tobin's q often correlates with higher GHG emissions across all industry sectors. This finding is contrary to evidence found in previous studies conducted in other countries. The positive correlation found in this study could be explained with reference to the unique economic structure and development of Australia, particularly its dominant mining industry.

Evaluation of facial expression in acute pain in cats

Abstract: OBJECTIVES To describe the development of a facial expression tool differentiating pain-free cats from those in acute pain. METHODS Observers shown facial images from painful and pain-free cats were asked to identify if they were in pain or not. From facial images, anatomical landmarks were identified and distances between these were mapped. Selected distances underwent statistical analysis to identify features discriminating pain-free and painful cats. Additionally, thumbnail photographs were reviewed by two experts to identify discriminating facial features between the groups. RESULTS Observers (n = 68) had difficulty in identifying pain-free from painful cats, with only 13% of observers being able to discriminate more than 80% of painful cats. Analysis of 78 facial landmarks and 80 distances identified six significant factors differentiating pain-free and painful faces including ear position and areas around the mouth/muzzle. Standardised mouth and ear distances when combined showed excellent discrimination properties, correctly differentiating pain-free and painful cats in 98% of cases. Expert review supported these findings and a cartoon-type picture scale was developed from thumbnail images. CLINICAL SIGNIFICANCE Initial investigation into facial features of painful and pain-free cats suggests potentially good discrimination properties of facial images. Further testing is required for development of a clinical tool

Diagnosing dying: an integrative literature review

Abstract: Background To ensure patients and families receive appropriate end-of-life care pathways and guidelines aim to inform clinical decision making. Ensuring appropriate outcomes through the use of these decision aids is dependent on timely use. Diagnosing dying is a complex clinical decision, and most of the available practice checklists relate to cancer. There is a need to review evidence to establish diagnostic indicators that death is imminent on the basis of need rather than a cancer diagnosis. Aim To examine the evidence as to how patients are judged by clinicians as being in the final hours or days of life. Design Integrative literature review. Data sources Five electronic databases (2001–2011): Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library, MEDLINE, EMBASE, PsycINFO and CINAHL. The search yielded a total of 576 hits, 331 titles and abstracts were screened, 42 papers were retrieved and reviewed and 23 articles were included. Results Analysis reveals an overarching theme of uncertainty in diagnosing dying and two subthemes: (1) ‘characteristics of dying’ involve dying trajectories that incorporate physical, social, spiritual and psychological decline towards death; (2) ‘treatment orientation’ where decision making related to diagnosing dying may remain focused towards biomedical interventions rather than systematic planning for end-of-life care. Conclusions The findings of this review support the explicit recognition of ‘uncertainty in diagnosing dying’ and the need to work with and within this concept. Clinical decision making needs to allow for recovery where that potential exists, but equally there is the need to avoid futile interventions.

Smart cities: the state-of-the-art and governance challenge

Abstract: Reflecting on the governance of smart cities, the state-of-the-art this paper advances offers a critique of recent city ranking and future Internet accounts of their development. Armed with these critical insights, it goes on to explain smart cities in terms of the social networks, cultural attributes and environmental capacities, vis-a-vis, vital ecologies of the intellectual capital, wealth creation and standards of participatory governance regulating their development. The Triple Helix model which the paper advances to explain these performances in turn suggests that cities are smart when the ICTs of future Internet developments successfully embed the networks society needs for them to not only generate intellectual capital, or create wealth, but also cultivate the environmental capacity, ecology and vitality of those spaces which the direct democracy of their participatory governance open up, add value to and construct.

Rapid Losses of Surface Elevation following Tree Girdling and Cutting in Tropical Mangroves

Abstract: The importance of mangrove forests in carbon sequestration and coastal protection has been widely acknowledged. Large-scale damage of these forests, caused by hurricanes or clear felling, can enhance vulnerability to erosion, subsidence and rapid carbon losses. However, it is unclear how small-scale logging might impact on mangrove functions and services. We experimentally investigated the impact of small-scale tree removal on surface elevation and carbon dynamics in a mangrove forest at Gazi bay, Kenya. The trees in five plots of a Rhizophora mucronata (Lam.) forest were first girdled and then cut. Another set of five plots at the same site served as controls. Treatment induced significant, rapid subsidence (−32.1±8.4 mm yr−1 compared with surface elevation changes of +4.2±1.4 mm yr−1 in controls). Subsidence in treated plots was likely due to collapse and decomposition of dying roots and sediment compaction as evidenced from increased sediment bulk density. Sediment effluxes of CO2 and CH4 increased significantly, especially their heterotrophic component, suggesting enhanced organic matter decomposition. Estimates of total excess fluxes from treated compared with control plots were 25.3±7.4 tCO2 ha−1 yr−1 (using surface carbon efflux) and 35.6±76.9 tCO2 ha−1 yr−1 (using surface elevation losses and sediment properties). Whilst such losses might not be permanent (provided cut areas recover), observed rapid subsidence and enhanced decomposition of soil sediment organic matter caused by small-scale harvesting offers important lessons for mangrove management. In particular mangrove managers need to carefully consider the trade-offs between extracting mangrove wood and losing other mangrove services, particularly shoreline stabilization, coastal protection and carbon storage.

Feature selection inspired classifier ensemble reduction.

Abstract: Classifier ensembles constitute one of the main research directions in machine learning and data mining. The use of multiple classifiers generally allows better predictive performance than that achievable with a single model. Several approaches exist in the literature that provide means to construct and aggregate such ensembles. However, these ensemble systems contain redundant members that, if removed, may further increase group diversity and produce better results. Smaller ensembles also relax the memory and storage requirements, reducing system's run-time overhead while improving overall efficiency. This paper extends the ideas developed for feature selection problems to support classifier ensemble reduction, by transforming ensemble predictions into training samples, and treating classifiers as features. Also, the global heuristic harmony search is used to select a reduced subset of such artificial features, while attempting to maximize the feature subset evaluation. The resulting technique is systematically evaluated using high dimensional and large sized benchmark datasets, showing a superior classification performance against both original, unreduced ensembles, and randomly formed subsets.

Resistance Exercise Increases Endothelial Progenitor Cells and Angiogenic Factors.

Abstract: ROSS, M. D., A. L. WEKESA, J. P. PHELAN, and M. HARRISON. Resistance Exercise Increases Endothelial Progenitor Cells and Angiogenic Factors. Med. Sci. Sports Exerc., Vol. 46, No. 1, pp. 16–23, 2014. Introduction: Bone marrow-derived endothelial progenitor cells (EPC) are involved in vascular growth and repair. They increase in the circulation after a single bout of aerobic exercise, potentially related to muscle ischemia. Muscular endurance resistance exercise (MERE) bouts also have the potential to induce muscle ischemia if appropriately structured. Purpose: The objective of this study is to determine the influence of a single bout of MERE on circulating EPC and related angiogenic factors. Methods: Thirteen trained men age 22.4 T 0.5 yr (mean T SEM) performed a bout of MERE consisting of three sets of six exercises at participants’ 15-repetition maximum without resting between repetitions or exercises. The MERE bout duration was 12.1 T 0.6 min. Blood lactate and HR were 11.9 T 0.9 mmolIL j1 and 142 T 5 bpm, respectively, at the end of MERE. Blood was sampled preexercise and at 10 min, 2 h, and 24 h postexercise. Results: Circulating EPC and serum concentrations of vascular endothelial growth factors (VEGF-A, VEGF-C, and VEGF-D), granulocyte colony stimulating factor, soluble Tie-2, soluble fms-like tyrosine kinase-1, and matrix metalloproteinases (MMP-1, MMP-2, MMP-3, MMP-9, and MMP-9) were higher (P G 0.05) in the postexercise period. Circulating EPC levels were unchanged at 10 min postexercise but higher at 2 h postexercise (P G 0.05). The concentration of most angiogenic factors and metalloproteinases were higher at 10 min postexercise (VEGF-A, +38%; VEGF-C, +40%; VEGF-D, +9%; soluble Tie-2, +15%; soluble fms-like tyrosine kinase-1, +24%; MMP-1, +62%; MMP-2, +3%; MMP-3, +54%; and MMP-9, +45%; all P G 0.05). Soluble E-selectin was lower (P G 0.05) at 2 and 24 h postexercise, with endothelial microparticles and thrombomodulin unchanged. Conclusions: Short intense bouts of MERE can trigger increases in circulating EPC and related angiogenic factors, potentially contributing to vascular adaptation and vasculoprotection.

Antiviral potential of cathelicidins.

Abstract: The global burden of morbidity and mortality arising from viral infections is high; however, the development of effective therapeutics has been slow. As our understanding of innate immunity has expanded over recent years, knowledge of natural host defenses against viral infections has started to offer potential for novel therapeutic strategies. An area of current research interest is in understanding the roles played by naturally occurring cationic host defense peptides, such as the cathelicidins, in these innate antiviral host defenses across different species. This research also has the potential to inform the design of novel synthetic antiviral peptide analogs and/or provide rationale for therapies aimed at boosting the natural production of these peptides. In this review, we will discuss our knowledge of the antiviral activities of cathelicidins, an important family of cationic host defense peptides, and consider the implications for novel antiviral therapeutic approaches.

Presence and digital tourism

Abstract: This paper provides an introduction to digital tourism as mediated by presence research as a means to create substantive user experiences (UX) for visitors. Tourism is a rich and varied socio-economic activity that permeates our global society. Digital tourism is the digital support of the tourist experience. In this paper we introduce and survey both fields and introduce a number of examples of tourist experiences based on our blended spaces approach. Cutting across this is the sense of presence that visitors can experience in real or digital tourist experiences. We conclude the paper with a discussion of designing the user experience in blended tourist spaces.

Modal analysis of pile-supported structures during seismic liquefaction

Abstract: The purpose of this paper is to investigate the effects of liquefaction on modal parameters (frequency and damping) of pile-supported structures. Four physical models, consisting of two single piles and two 2 × 2 pile groups, were tested in a shaking table where the soil surrounding the pile liquefied because of seismic shaking. The experimental results showed that the natural frequency of pile-supported structures may decrease considerably owing to the loss of lateral support offered by the soil to the pile. On the other hand, the damping ratio of structure may increase to values in excess of 20%. These findings have important design consequences: (a) for low-period structures, substantial reduction of spectral acceleration is expected; (b) during and after liquefaction, the response of the system may be dictated by the interactions of multiple loadings, that is, horizontal, axial and overturning moment, which were negligible prior to liquefaction; and (c) with the onset of liquefaction due to increased flexibility of pile-supported structure, larger spectral displacement may be expected, which in turn may enhance P-delta effects and consequently amplification of overturning moment. Practical implications for pile design are discussed.

Noteworthy Matters for Attention in Reflective Journal Writing.

Abstract: The principles advocated in the widely acclaimed keynote texts on reflection have nominally been followed for over 30 years in educational programmes and schemes for professional development. This article was prompted by the impression that practice and theorising reported in publications about journal writing does not consistently endorse the advice in the seminal literature, and is potentially confusing for those who seek advice and direction. In particular, some writers tolerate or encourage narrative reporting without significant reflection thereon; many articles only feature aspects of the reflective cycle, and metacognitive forward planning that aims to validate the emerging generalisation is often neglected. Noteworthy matters are identified for attention and suggestions made for an approach that today’s journal writers and their mentors may find useful to employ, in order to better focus reflections and validate their generalisations.

Clarifying misconceptions about compassionate care.

Abstract: Aim To discuss the meaning of compassionate care as it applies to staff, patients and families in health and social care settings, its application to practice and how organizational infrastructures affect the delivery of care. Background The term compassion has assumed headline status and inclusion in current health and social care policy. Clarity of what the term means in practice is needed and may help to promote delivery of compassionate care consistently across health and social care settings. Design Discussion paper. Data Sources This article draws on data from an action research programme (Leadership in Compassionate Care Programme, 2007–2011) that focused on embedding compassionate care into practice and education and related literature focused on compassionate person-centred care. A literature search was conducted and articles published in English relating to the terms compassionate, person-centred care between 1999–2011 were included. Discussion Perceptions of compassion, practising compassion and the infrastructure to support compassion are discussed. Implications for Nursing It is anticipated that this discussion will prompt further debate, raise awareness and help to clarify the meaning of compassion in everyday practice with patients, relatives and staff, so that it can be more clearly named, valued and defended. Conclusion This article challenges some of the beliefs and values that underpin the meaning of compassionate care and its application to practice. It brings greater clarity to the meaning of compassion, which could be used to form the basis of shared visions of caring, both strategic and operational, across organizations.

Development of a behaviour‐based measurement tool with defined intervention level for assessing acute pain in cats

Abstract: OBJECTIVES To develop a composite measure pain scale tool to assess acute pain in cats and derive an intervention score. METHODS To develop the prototype composite measure pain scale-feline, words describing painful cats were collected, grouped into behavioural categories and ranked. To assess prototype validity two observers independently assigned composite measure pain scale-feline and numerical rating scale scores to 25 hospitalised cats before and after analgesic treatment. Following interim analysis the prototype was revised (revised composite measure pain scale-feline). To determine intervention score, two observers independently assigned revised composite measure pain scale-feline and numerical rating scale scores to 116 cats. A further observer, a veterinarian, stated whether analgesia was necessary. RESULTS Mean ± sd decrease in revised composite measure pain scale-feline and numerical rating scale scores following analgesia were 2 · 4 ± 2 · 87 and 1 · 9 ± 2 · 34, respectively (95% confidence interval for mean change in revised composite measure pain scale-feline between 1 · 21 and 3 · 6). Changes in revised composite measure pain scale-feline and numerical rating scale were significantly correlated (r = 0 · 8) (P < 0001). Intervention level score of ≥4/16 was derived for revised composite measure pain scale-feline (26 · 7% misclassification) and ≥3/10 for numerical rating scale (14 · 5% misclassification). CLINICAL SIGNIFICANCE A valid instrument with a recommended analgesic intervention level has been developed to assess acute clinical pain in cats that should be readily applicable in practice.

Habitat segregation by female humpback whales in Hawaiian waters: avoidance of males?

Abstract: Humpback whales congregate annually in low-latitude winter breeding and calving grounds. While on these grounds, females with a dependent calf (‘maternal females’) are sometimes closely attended by one or more male escorts. Using data collected from a shore-based observation platform in the Hawaiian Islands, we tested the hypothesis that the spatial distribution of maternal females is driven primarily by avoidance of males. As predicted, we found that (1) pods containing a calf occurred in significantly shallower water than pods that did not contain a calf, (2) unescorted maternal females occurred in significantly shallower water than escorted maternal females, (3) the number of males escorting a female decreased significantly with decreasing water depth, and (4) the swimming speed of maternal females increased as a function of male presence, with escorted females travelling significantly more rapidly than unescorted females and a significant positive correlation between swimming speed and number of escorts. We suggest that maternal females incur increased energetic costs when escorted by males and consequently position themselves in shallow waters to reduce the likelihood of unwanted male attention.

Gastro-tourism as destination branding in emerging markets

Abstract: Gastro-tourism, a niche that attracts billions in revenue worldwide, involves intentional pursuits of authentic memorable culinary experiences while travelling internationally, regionally or locally. For gastro-tourists, food is the motivation for travel; the locations merely functions as vehicles for gastronomic experiences (food-related-activities that involve behind-the-scenes observations, cultural/regional illuminations and often hands-on participation, culminating in partaking food or drink.) This paper identifies three phases of travel and corresponding elements essential for the creation of new gastro-tourism enterprises. It introduces the significance of shared Gastro-Tourism Brand Promises, agreed upon, cross marketed, and fulfilled by individual hosts, groups/networks, and regional/government entities. By providing basic infrastructure elements – health, safety, transportation and communication; identifying loosely organised home-grown resources and talent; creating and marketing shared brand promises; and incorporating ongoing feedback during three travel phases; emerging markets in underdeveloped countries and underdeveloped pockets in developed nations can ignite and maintain successful gastro-tourist enterprises.

A unified hyper-heuristic framework for solving bin packing problems

Abstract: One- and two-dimensional packing and cutting problems occur in many commercial contexts, and it is often important to be able to get good-quality solutions quickly. Fairly simple deterministic heuristics are often used for this purpose, but such heuristics typically find excellent solutions for some problems and only mediocre ones for others. Trying several different heuristics on a problem adds to the cost. This paper describes a hyper-heuristic methodology that can generate a fast, deterministic algorithm capable of producing results comparable to that of using the best problem-specific heuristic, and sometimes even better, but without the cost of trying all the heuristics. The generated algorithm handles both one- and two-dimensional problems, including two-dimensional problems that involve irregular concave polygons. The approach is validated using a large set of 1417 such problems, including a new benchmark set of 480 problems that include concave polygons.

Recovering from childhood sexual abuse: a theoretical framework for practice and research

Abstract: Research on survivors' experiences of recovering from childhood sexual abuse (CSA) has been limited and focused on those with severe mental health difficulties. This study elicited experiences of recovery from CSA in male and female survivors who have/have not utilized mental health services. The tangible end-point was to propose a theoretical model of personally meaningful recovery. This is a qualitative study, which utilized semi-structured individual interviews following the critical incident technique. Transcripts were analysed using Interpretative Phenomenological Analysis to identify recurrent themes. A total 22 adult survivors of CSA. Main themes identified were: The Affected Self, Factors Hindering Recovery, Factors Enhancing Recovery, The Hurdles of Recovery and the Recovering Self. The affected self included: lack of boundary awareness and self-blame, over self-reliance, over-vigilance and guilt, shame, aloneness and social stigma. The recovering self was characterized by increasing confidence, assertiveness, ability to self-care and self-acceptance, and by embracing vulnerability. These findings have potentially major implications for clinical practice, service provision, policy development and professional training in this field. The importance of disclosure in the healing process seemed paramount and can have major implications for current service protocols.

Illusion or delusion – Lean management in the health sector

Abstract: Purpose – There has been considerable interest in the implementation of practices imported from manufacturing into healthcare as a solution to rising healthcare spending and disappointing patient safety indicators. One approach that has attracted particular interest is Lean management and the purpose of this paper is to engage with this topic. Design/methodology/approach – Secondary research. Findings – Despite widespread enthusiasm about the potential of Lean management processes, evidence about its contribution to higher organisational performance remains inconsistent. Research limitations/implications – This paper engages with the major Lean concepts of operations management and human resource management, including just-in-time, total quality management, total productive maintenance and does not engage in-depth with concepts related to employee empowerment, and training. Practical implications – This paper contributes to the organisational management literature in healthcare by showing that although Le...

Absorbing new knowledge in small and medium-sized enterprises: A multiple case analysis of Six Sigma

Abstract: The primary aim of this article is to critically analyse the development of Six Sigma theory and practice within small and medium-sized enterprises (SMEs) using a multiple case study approach. The article also explores the subsequent development of Lean Six Sigma as a means of addressing the perceived limitations of the efficacy of Six Sigma in this context. The overarching theoretical framework is that of absorptive capacity, where Six Sigma is conceptualized as new knowledge to be absorbed by smaller firms. The findings from a multiple case study involving repeat interviews and focus groups informed the development of an analytical model demonstrating the dynamic underlying routines for the absorptive capacity process and the development of a number of summative propositions relating the characteristics of SMEs to Six Sigma and Lean Six Sigma implementation.

Spaces of Interaction, Places for Experience

Abstract: Spaces of Interaction, Places for Experience is a book about Human-Computer Interaction (HCI), interaction design (ID) and user experience (UX) in the age of ubiquitous computing The book explores interaction and experience through the different spaces that contribute to interaction until it arrives at an understanding of the rich and complex places for experience that will be the focus of the next period for interaction design The book begins by looking at the multilayered nature of interaction and UXnot just with new technologies, but with technologies that are embedded in the world People inhabit a medium, or rather many media, which allow them to extend themselves, physically, mentally, and emotionally in many directions The medium that people inhabit includes physical and semiotic material that combine to create user experiences People feel more or less present in these media and more or less engaged with the content of the media From this understanding of people in media, the book explores some philosophical and practical issues about designing interactions The book journeys through the design of physical space, digital space, information space, conceptual space and social space It explores concepts of space and place, digital ecologies, information architecture, conceptual blending and technology spaces at work and in the home It discusses navigation of spaces and how people explore and find their way through environments Finally the book arrives at the concept of a blended space where the physical and digital are tightly interwoven and people experience the blended space as a whole The design of blended spaces needs to be driven by an understanding of the correspondences between the physical and the digital, by an understanding of conceptual blending and by the desire to design at a human scale There is no doubt that HCI and ID are changing The design of microinteractions remains important, but there is a bigger picture to consider UX is spread across devices, over time and across physical spaces The commingling of the physical and the digital in blended spaces leads to new social spaces and new conceptual spaces UX concerns the navigation of these spaces as much as it concerns the design of buttons and screens for apps By taking a spatial perspective on interaction, the book provides new insights into the evolving nature of interaction design
